Direct Known Subclasses:: BasicDirectoryModel, DefaultComboBoxModel, DefaultListModel, MetalFileChooserUI.DirectoryComboBoxModel, MetalFileChooserUI.FilterComboBoxModel

public abstract class AbstractListModel
extends Object
implements ListModel, Serializable

The Abstract definition for the data model the provides a List with its contents.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. A future release of Swing will provide support for long term persistence.

Method Detail

addListDataListener

public void addListDataListener(ListDataListener l)

Add a listener to the list that's notified each time a change to the data model occurs.

Specified by:: addListDataListener in interface ListModel

Parameters:: l - the ListDataListener

removeListDataListener

public void removeListDataListener(ListDataListener l)

Remove a listener from the list that's notified each time a change to the data model occurs.

Specified by:: removeListDataListener in interface ListModel

Parameters:: l - the ListDataListener

fireContentsChanged

protected void fireContentsChanged(Object source,
                                   int index0,
                                   int index1)

AbstractListModel subclasses must call this method after one or more elements of the list change. The changed elements are specified by a closed interval index0, index1, i.e. the range that includes both index0 and index1. Note that index0 need not be less than or equal to index1.

Parameters:: source - The ListModel that changed, typically "this".; index0 - One end of the new interval.; index1 - The other end of the new interval.
See Also:: EventListenerList, DefaultListModel

fireIntervalAdded

protected void fireIntervalAdded(Object source,
                                 int index0,
                                 int index1)

AbstractListModel subclasses must call this method after one or more elements are added to the model. The new elements are specified by a closed interval index0, index1, i.e. the range that includes both index0 and index1. Note that index0 need not be less than or equal to index1.

Parameters:: source - The ListModel that changed, typically "this".; index0 - One end of the new interval.; index1 - The other end of the new interval.
See Also:: EventListenerList, DefaultListModel

fireIntervalRemoved

protected void fireIntervalRemoved(Object source,
                                   int index0,
                                   int index1)

AbstractListModel subclasses must call this method after one or more elements are removed from the model. The new elements are specified by a closed interval index0, index1, i.e. the range that includes both index0 and index1. Note that index0 need not be less than or equal to index1.

Parameters:: source - The ListModel that changed, typically "this".; index0 - One end of the new interval.; index1 - The other end of the new interval.
